DIRECT QUADRATURE MODULATOR

Product Description

The RF2480 is a monolithic integrated quadrature modu-

lator IC capable of universal direct modulation for high-

frequency AM, PM, or compound carriers. This low-cost

IC features excellent linearity, noise floor, and over-tem-

perature carrier suppression performance. The device

implements differential amplifiers for the modulation

inputs, 90擄 carrier phase shift network, carrier limiting

amplifiers, two matched double-balanced mixers, sum-

ming amplifier, and an output RF amplifier which will drive

50鈩?from 800MHz to 2500MHz. Component matching is

used to obtain excellent amplitude balance and phase

accuracy.
